====== AMP Command ====== AMP,,,,,,,,,,, adds non-zero parameters to spectral amplification ratio list of input motion for the multiple excitation option - ACS SASSI [[SASSI:HOUSE]] module or deletes spectral amplification ratios if is zero. Note: This instruction is provided for input files. To change spectral amplification ratios from the ACS SASSI [[SASSI:PREP]] and [[SASSI:acs-sassi_user_interface| ACS-SASSI User Interface]], use the Options / Analysis command.
